Add deprecation warning for each renamed variant.
However, it will just fail to compile if the deprecated variant is used
inside a match statement. It is not possible to make aliases of variants
in Rust.
Implement new_line(), calc_text_size(), and with_style_var_pushed_*()
methods I needed while making a demo.
I'm pretty new to Rust, but ran into this issue and thought I could
maybe solve it while I was learning the library.

I'm curious on your thoughts on these additions. Please LMK if you would
prefer a different direction, I'm pretty new to both Rust and this
library so please let me know if you have any suggestions!
I'm hoping to contribute to this library moving forward, as I work on
my game's UI.
